+# Changelog
+
+## Unreleased
+
+### Added
+
+- `~/.config/chopsticks.vim` local pre-load config for profile and user choices
+- `g:chopsticks_enable_markdown_preview` to control Previm independently
+- `g:chopsticks_profile` with `minimal`, `engineer`, and `full` profiles
+- `.markdownlint.json` aligned with the project's README/changelog style
+- `:ChopsticksStatus` diagnostic command — checks system tools, LSP servers, linters, formatters
+- `,af` toggle format-on-save (ALE `fix_on_save`)
+- `,gL` git log graph (last 20 commits)
+- `,gC` FZF git commits search, `,gB` buffer commits
+- Interactive installer profile selection for `minimal`, `engineer`, and `full`
+- `install.sh --profile=minimal|engineer|full` for scripted profile selection
+- `install.sh --dry-run` to show the resolved profile/config path without writes
+- `install.sh --configure-only` to update local profile config without reinstalling
+- `get.sh --dry-run` for safe bootstrap previews before clone/update/install
+- `CHOPSTICKS_DEST=/absolute/path` to test or install the bootstrap target elsewhere
+- `scripts/test.sh` local test runner reused by GitHub Actions
+- `scripts/test.sh quick`, `--help`, and `list` for easier local test discovery
+
+### Fixed
+
+- `g:loaded_logipat` typo → `g:loaded_logiPat` — logiPat was loading fully (0.478ms wasted)
+- `get.sh` now refuses to update an existing `~/.vim` git repo unless its
+  origin is chopsticks
+- Large file protection now stays active after filetype and syntax autocommands
+- `g:ale_fix_on_save = 0` in local config is now respected
+- Local config now respects absolute `XDG_CONFIG_HOME` instead of hardcoding
+  `~/.config`
+
+### Changed
+
+- `,?` cheat sheet is now profile-aware and hides LSP/ALE/preview/UndoTree keys
+  when those features are disabled
+- Module reload/source paths now use `fnameescape()` so installs in paths with
+  spaces are handled correctly
+- CI now verifies path-safe module loading, the local config hook, and
+  minimal-profile cheat sheet output
+- Markdown now opens in quiet writing mode by default: no real-time markdownlint,
+  no Marksman LSP, no spell noise, no conceal, no sign column, and no realtime preview
+- Native `s` is no longer shadowed by EasyMotion; use `,S` for the two-character jump
+- `,w` now uses a normal `:write` instead of forced `:write!`
+- Swap files are enabled again and stored under `~/.vim/.swap` for crash recovery
+- Installer defaults are slimmer: only core search tools stay selected by default;
+  language and lint suites are opt-in
+- `:ChopsticksStatus` now respects disabled LSP/lint profiles instead of reporting
+  intentionally disabled tools as missing
+- `,sv` now clears the load guard before sourcing `$MYVIMRC`
+- CI now verifies key plugin directories, Markdown quiet defaults, markdownlint,
+  and an explicit startup-time threshold
+- Installer plugin validation now checks every plugin required by the active profile
+- The optional tool menu now hides LSP/lint suites in `minimal` and selects
+  Marksman by default in `full`
+- tmux integration is written as a managed block so future installer runs can
+  update it without appending duplicate bindings
+- Installer cleanup now restores the cursor after interrupted checkbox menus
+- Bootstrap dry-run now refuses unrelated existing git repos before any writes
+- CI now shares shell, installer, bootstrap, docs, and Vim smoke checks with
+  the local test runner
+- CI now checks the test runner help and group-list commands
+- Skip 2 more built-in plugins: openPlugin, manpager (10 → 12 total)
+- Remove deprecated `set ttyfast` (no-op since Vim 8)
+- Add `grepprg=rg --vimgrep` — `:grep` now uses ripgrep + quickfix
+- Add `diffopt` with histogram algorithm and indent-heuristic
+- Consolidate FZF Rg/RgWord/GFiles commands (DRY refactor)
+- vim-tmux-navigator: conditional load (only inside tmux), fallback `Ctrl+hjkl` mappings outside
+- Add `Ctrl+hjkl` window navigation fallback when tmux-navigator not loaded
+

+
+### Removed (Unix minimalism refactor)

 ## Rules

 1. **No Node.js dependencies.** The LSP engine is pure VimScript. Some language servers need Node — that's fine. The config itself must not.
-2. **Startup matters.** Run `vim --startuptime /tmp/s.log -c qa!` before and after. If your change adds >1ms, it needs a good reason.
+2. **Startup matters.** Run `vim -u .vimrc -i NONE --startuptime /tmp/s.log -es -N -c qa!` before and after. If your change adds >1ms, it needs a good reason.
 3. **Works on TTY.** Test over SSH. If it breaks in a terminal without true color, fix it or gate it behind `g:is_tty`.
 4. **One module, one concern.** Don't put git config in lsp.vim.

+scripts/test.sh quick

+`scripts/test.sh quick` runs shell, docs, installer, and bootstrap checks without requiring Vim plugins.
+`scripts/test.sh vim` expects plugins to be installed under `~/.vim/plugged`.
+Use `STARTUP_LIMIT_MS=150 scripts/test.sh vim` to match CI's startup threshold.

 ## Install

 ```bash
 curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --profile=minimal
+curl -fsSL https://raw.githubusercontent.com/m1ngsama/chopsticks/main/get.sh | bash -s -- --dry-run --profile=full
 ```

 Or manually:

 ```bash
 git clone https://github.com/m1ngsama/chopsticks.git ~/.vim
-cd ~/.vim && ./install.sh
+cd ~/.vim && ./install.sh --profile=engineer
 ```

 Supports macOS (brew), Debian/Ubuntu (apt), Arch (pacman), Fedora (dnf).
+Set `CHOPSTICKS_DEST=/absolute/path` before running `get.sh` to install
+somewhere other than `~/.vim`.

 First launch installs plugins automatically (30-60s). Restart vim when done.
+Use `./install.sh --dry-run --profile=full` to inspect the resolved profile and
+config path without changing files. Use `./install.sh --configure-only
+--profile=minimal` to switch profiles without reinstalling plugins or tools.
+
+## Profiles
+
+Default profile: `engineer`. Interactive installs ask for this profile before
+plugins are installed; `--profile=minimal`, `--profile=engineer`, or
+`--profile=full` selects it without prompting. `--yes` keeps the existing local
+profile or uses `engineer`.
+
+```vim
+" Put this in ${XDG_CONFIG_HOME:-~/.config}/chopsticks.vim.
+let g:chopsticks_profile = 'minimal'   " core navigation/editing/git/markdown
+let g:chopsticks_profile = 'engineer'  " default: LSP, ALE, syntax extras
+let g:chopsticks_profile = 'full'      " engineer + heavier Markdown feedback
+```
+
+`minimal` avoids LSP, ALE, completion plugins, extra language syntax plugins,
+Startify, UndoTree, and browser Markdown preview. `full` keeps those and opts
+into Markdown lint, format, spell, conceal, Marksman, and LSP virtual text.
+
+Project updates leave `~/.config/chopsticks.vim` alone, so put local choices
+there instead of editing the managed `.vimrc`. The `,?` cheat sheet follows the
+active profile and only shows keys for enabled features.

+pylsp, gopls, rust-analyzer, clangd, sqls — no Node.js. JS/TS servers need Node.
+Markdown LSP (`marksman`) is opt-in so prose buffers stay quiet by default.

 ALE and vim-lsp coexist cleanly (`ale_disable_lsp=1`). ALE handles linting + formatting. vim-lsp handles everything else.

+## Markdown
+
+Markdown opens in writing mode: wrapped text, no spell noise, no concealed
+syntax, no sign column, no real-time markdownlint, and no Marksman diagnostics.
+The explicit commands still work:
+
+```vim
+,mp    " preview in browser
+,mt    " table of contents
+```
+
+Opt into heavier Markdown tooling from your own vimrc before loading
+chopsticks:
+
+```vim
+let g:chopsticks_markdown_lint = 1
+let g:chopsticks_markdown_format_on_save = 1
+let g:chopsticks_markdown_lsp = 1
+let g:chopsticks_markdown_spell = 1
+let g:chopsticks_markdown_conceal = 1
+let g:previm_enable_realtime = 1
+```
+
+For Markdown LSP, install or select `marksman` first.

-This tutorial teaches the key features of the chopsticks Vim configuration.
-It assumes you already know basic Vim (if not, run :Tutor first).
-
-Leader key is , (comma) throughout this tutorial.
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 1: SURVIVAL BASICS
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-These four commands get you out of any situation:
-
-  1. Press  Esc  or type  jk  to return to Normal mode
-  2. Type  ,w   to save the current file
-  3. Type  ,x   to save and quit
-  4. Type  ,q   to quit (without saving)
-
-TIP: You can also press  Ctrl+s  to save from ANY mode (normal, insert,
-     or visual). Try it now — press  i  to enter insert mode, then  Ctrl+s
-     to save without leaving insert mode.
-
-When completely lost, press  ,?  to open the cheat sheet with every
-keybinding. Press  q  to close it.
-
-     >>> Try it now: press  ,?  then read through the sheet, then press  q
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 2: FINDING FILES
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-chopsticks uses FZF (fuzzy finder) for fast navigation.
-
-  Ctrl+p    Fuzzy find files (git-aware — ignores .gitignore'd files)
-  ,b        Search open buffers
-  ,fh       Recent file history
-  ,rg       Search file contents with ripgrep
-  ,rG       Search for the word under your cursor
-
-     >>> Try it now: press  Ctrl+p  and start typing a filename
-
-You can also browse files with the built-in file browser:
-
-  ,e        Open netrw file browser in current window
-  ,E        Open netrw in a vertical split
-
-Inside netrw:
-  Enter     Open file
-  -         Go up one directory
-  %         Create new file
-  d         Create new directory
-  gh        Toggle hidden files
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 3: CODE INTELLIGENCE
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-chopsticks uses vim-lsp for code intelligence — no Node.js required.
-
-First, install a language server for your filetype:
-
-  :LspInstallServer      (auto-detects the language)
-  :LspStatus             (check if it's running)
-
-Once a server is running, these keys become available:
-
-  gd        Go to definition
-  gy        Go to type definition
-  gi        Go to implementation
-  gr        List all references
-  K         Show hover documentation
-
-  [g / ]g   Jump to previous / next diagnostic
-  ,rn       Rename symbol under cursor
-  ,ca       Code action (auto-fix)
-  ,f        Format buffer (or selection in visual mode)
-  ,o        File outline (symbols)
-
-     >>> Open a source file and try:  gd  on a function call, then  Ctrl+o
-         to jump back
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 4: EDITING POWER
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-These editing features make chopsticks faster than vanilla Vim.
-
-EASYMOTION — jump anywhere on screen:
-  Press  s  then type two characters from your target location.
-  Matching positions light up — press the highlighted letter to jump.
-
-     >>> Try it now: press  s  then type two letters you can see on screen
-
-MOVE LINES — rearrange code without cut/paste:
-  Alt+j     Move current line down
-  Alt+k     Move current line up
-  (Works in visual mode too — select lines first with  V )
-
-SURROUND — change surrounding characters:
-  cs"'      Change surrounding " to '
-  cs'<div>  Change surrounding ' to <div>...</div>
-  ds(       Delete surrounding parentheses
-  ysiw"     Surround word with "
-
-COMMENT — toggle comments:
-  gc        Toggle comment (works in visual mode on selections)
-  gcc       Toggle comment on current line
-
-VISUAL FEEDBACK:
-  - Yanked text flashes briefly so you know what was copied
-  - Search highlights auto-clear after you stop moving
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 5: GIT WORKFLOW
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-All git operations through vim-fugitive:
-
-  ,gs       Git status (press  s  to stage, press  cc  to commit)
-  ,gd       Diff current file (side-by-side split)
-  ,gb       Git blame (who changed each line)
-  ,gc       Git commit
-  ,gp       Git push
-  ,gl       Git pull
-
-GitGutter shows changes in the sign column (left margin):
-  +  Added line
-  ~  Modified line
-  -  Deleted line
-
-Navigate git conflict markers:
-  ]x        Jump to next conflict marker
-  [x        Jump to previous conflict marker
-
-     >>> Try  ,gs  in a git repository to see the status view
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 6: MARKDOWN & WRITING
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Markdown files get special treatment automatically:
-  - Word wrap enabled
-  - Spell checking enabled
-  - Syntax concealment (bold renders as bold, headings hide # markers)
-  - Folding by heading level
-
-Key bindings for markdown:
-
-  ,mp       Open live browser preview (auto-refreshes as you type)
-  ,mt       Table of contents in a side window
-  ,zen      Enter zen mode — Goyo + Limelight
-              (distraction-free writing, only current paragraph highlighted)
-  zr        Unfold all headings
-  zm        Fold all headings
-
-     >>> Open a .md file and try  ,zen  to enter zen mode.
-         Press  ,zen  again to leave.
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 7: WINDOW MANAGEMENT
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Navigate between splits (works with tmux panes too):
-
-  Ctrl+h    Move to left split
-  Ctrl+j    Move to split below
-  Ctrl+k    Move to split above
-  Ctrl+l    Move to right split
-
-Buffer navigation:
-
-  ,h        Previous buffer
-  ,l        Next buffer
-  ,bd       Close buffer (keeps window layout)
-  ,,        Switch to last file (toggle between two files)
-
-Window tricks:
-
-  ,z        Maximize current window (press again to restore)
-  ,= / ,-   Resize window height (bigger / smaller)
-  ,+ / ,_   Resize window width (bigger / smaller)
-
-Terminal:
-
-  ,tv       Open terminal (vertical split)
-  ,th       Open terminal (horizontal, 10 rows)
-  Esc Esc   Exit terminal mode back to normal
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 8: LINTING & FORMATTING
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-ALE runs linters and formatters automatically:
-
-  - Linting happens as you type (normal mode) and on save
-  - Format-on-save is enabled by default (black, prettier, gofmt, etc.)
-
-Navigate errors:
-
-  [e / ]e       Previous / next ALE error
-  ,aD           Show error detail in a popup
-
-Supported out of the box:
-  Python:     flake8 + pylint (lint), black + isort (format)
-  JS/TS:      eslint (lint), prettier + eslint (format)
-  Go:         staticcheck (lint), goimports (format)
-  Rust:       cargo (lint), rustfmt (format)
-  Shell:      shellcheck (lint)
-  And more:   yaml, dockerfile, css, markdown, sql
-
-     >>> Write some intentionally bad code and watch the sign column
-         light up with  X  (error) and  !  (warning) markers
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 9: RUNNING CODE
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Press  ,cr  to run the current file. It auto-detects the language:
-
-  Python     →  python3 file.py
-  JavaScript →  node file.js
-  TypeScript →  npx ts-node file.ts
-  Go         →  go run file.go
-  Rust       →  cargo run
-  Shell      →  bash file.sh
-  C          →  gcc + run
-  Lua, Ruby, Perl also supported
-
-     >>> Create a test file (e.g. test.py with: print("hello"))
-         and press  ,cr  to run it
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-                         Lesson 10: DAILY TIPS
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-SEARCH AND REPLACE:
-  ,*        Replace word under cursor throughout the file
-  //        In visual mode, search for selected text
-
-USEFUL SHORTCUTS:
-  Y         Yank to end of line (consistent with D and C)
-  ,y / ,Y   Yank to system clipboard
-  ,F        Re-indent entire file
-  ,W        Strip all trailing whitespace
-  :w!!      Sudo save (when you forgot to open as root)
-  ,ev       Edit your vimrc
-  ,sv       Reload your vimrc
-
-SESSIONS:
-  :Obsess         Start recording session (auto-restores next time)
-  :Obsess!        Stop recording
-
-The startup screen (Startify) shows recent files, sessions, and bookmarks.
-
-     >>> Press  ,?  one more time to review the full cheat sheet.
-         You now know the essential chopsticks features. Happy editing!
